My scientific areas are mainly focused on the study of the role of the mineral structures of phytoplankton on the degradation of organic matter (OM). We know that the particulate OM is linked to mineral structure in aggregates and that such relations change kinetics of mineral dissolution and, in turn, kinetics of degradation. The model studied is the frustule of diatoms (silica cell wall of diatoms) that can form aggregates sinking out of the photic layer and carrying OM. Relations between OM and frustules can varied from species to species and can explained variability in Si/OC coefficient found in different oceanic basins. To understand these relations and the effects of environmental variability (e.g nutrients availability) on the frustule, I carry out degradation experiment of diatoms grown under different conditions and I analyze the OM of the isolated frustules. |
